Background Decreased level of consciousness is a rare neurological manifestation of spontaneous intracranial hypotension (SIH), which typically presents with orthostatic headache. The optimal management of this uncommon presentation remains uncertain. Methods We analyzed the presentation, management and outcome of two patients in our institution and reviewed 22 patients reported in the literature with SIH and decreased level of consciousness, defined as any decrease in the patient’s Glasgow Coma Scale score. Results There were 20 male and four female patients (M:F ratio of 5:1) with an average age of 52 years (range 37 to 68 years). There was a variable time interval of up to many months between the initial presentation of SIH and changes in the level of consciousness. An epidural autologous blood patch was eventually successful in 79% of the patients, although up to three trials were necessary in seven of these patients. Intrathecal saline infusion used as a temporizing measure resulted in excellent response within hours in five out of six patients who received this treatment. Drainage of the subdural collection either did not result in any sustained improvement or resulted in clinical deterioration in 12 out of 12 patients who received this treatment. Conclusions In the absence of a clinical trial because of the rarity of this entity, the treatment of SIH complicated by decreased level of consciousness remained controversial in the past. However, current collective experience supports early treatment of patients with SIH and decreased level of consciousness with one or more epidural blood patches. Fibrin glue and surgical duroplasty are the next steps in the management of patients in whom epidural blood patches fail. Drainage of the subdural collections may be detrimental.

Proper Diagnosis

Spontaneous intracranial hypotension is a condition that affects young and middle-aged individuals. Women are more frequently affected than men. It is associated with severe positional headache without previous dural puncture and is often confused with other common headache conditions. Delay in diagnosis of the condition may predispose patients to severe complications. Many radiodiagnostic tools carry important risks to patients, including nerve injury and iatrogenic spinal cord injury. Imaging studies must be correlated with a detailed medical history and a thorough physical examination. Epidural blood patch, the mainstay of treatment, may require multiple attempts with increasing amounts of autologous blood. Increased awareness of spontaneous intracranial hypotension will likely contribute to its proper diagnosis and treatment.

Headache Relief

Background: Spontaneous intracranial hypotension (SIH) results from leaks developing in the dura mater. The major symptom is orthostatic headache which gradually disappears after lying down. Lumbar epidural blood patches (EBPs) can be effective in relieving headaches, however, thoracic and cervical EBPs have also been applied to alleviate the symptoms. Objective and Methods: Retrospective collection of the main characteristics of SIH, site and amount of blood injection, and clinical outcomes of 18 patients who underwent thoracic EBPs for intractable SIH. { Study Design: Retrospective case series Results: All thoracic autologous EBPs except 3 were performed in the sitting position. Patients undergoing epidural puncture at lower thoracic levels (T10-T12) received 25 mL of autologous blood, 15 mL and 18 mL were injected at spinal segments T5-T7 (mid-thoracic) and T2-T4 (upperthoracic), respectively. Thoracic EBPs did not lead to immediate resolution of symptoms in 3 of 18 patients; one of them underwent early repetition with complete headache relief, one refused a second EBP, and one experienced partial resolution, followed by a recurrence, and then satisfactory improvement with a second high thoracic EBP. In long-term follow-up only 2 patients complained of symptoms or relapses. Limitations: Retrospective nature of the case series, single center experience. Conclusions: Performing thoracic-targeted EBPs as the preferred approach theoretically improves results with respect to those observed with lumbar EBPs. The immediate response was comparable with that of other reports, but the long-term success rate (90%) turned out to be very effective in terms of both quality of headache relief and very low incidence of recurrence.

Csf Leakage

Object Spontaneous intracranial hypotension (SIH) is a potentially serious pathological syndrome consisting of specific symptoms and neuroradiological signs that can sometimes be used to assess the efficacy of the treatment. In this paper the authors report a series of 28 patients with this syndrome who were all treated with an epidural blood patch at the authors' institution. The authors propose a novel physiopathological theory of SIH based on some anatomical considerations about the spinal venous drainage system. Methods Between January 1993 and January 2007, the authors treated 28 patients in whom SIH had been diagnosed. Twenty-seven of the 28 patients presented with the typical findings of SIH on brain MR imaging (dural enhancement and thickening subdural collections, caudal displacement of cerebellar tonsils, and reduction in height of suprachiasmatic cisterns). The sites of the patients' neuroradiologically suspected CSF leakage were different, but the blood patch procedure was performed at the lumbar level in all patients. The patients were then assessed at 3-month and 1- and 3-year follow-up visits. At the last visit (although only available for 11 patients) 83.3% of patients were completely free from clinical symptoms and 8.3% complained of sporadic orthostatic headache. Results The authors think that in the so-called SIH syndrome, the dural leak, even in those cases in which it can be clearly identified on neuroradiological examinations, is not the cause of the disease but the effect of the epidural hypotension maintained by the inferior cava vein outflow to the heart. The goal of their blood patch procedure (a sort of epidural block obtained using autologous blood and fibrin glue at the L1–2 level) is not to seal CSF leaks, but instead to help in reversing the CSF-blood gradient within the epidural space along the entire cord. Conclusions The authors' procedure seems to lead to good and long-lasting clinical results.

Abstract Background: Spontaneous intracranial hypotension (SIH) is a secondary headache that has been attributed to a cerebrospinal fluid (CSF) leak. It may resolve spontaneously or require conservative treatment. An epidural blood patch (EBP) with autologous blood is performed in cases exhibiting an inadequate response to conservative methods. Rebound intracranial hypertension (RIH) can develop following an EBP in up to 27% of patients. It is characterized by a change in the headache features and is often accompanied by nausea, blurred vision. and diplopia. Symptoms commonly begin within the first 36 hours, but could develop over days to weeks. It is important to differentiate this rebound phenomenon from unimproved SIH, as the treatment options differ. Case presentation: Here we present an interesting case of a patient with SIH who was treated with EBP and developed both immediate RIH after 24 hours and delayed RIH 3 weeks following EBP. Conclusions: Following EBP for treatment of SIH, new onset of a headache having a different pattern and location should always be monitored for the occurrence of a RIH. A lumbar puncture should be done if the symptoms of elevated CSF pressure become intolerable or if the diagnosis is uncertain. Lack of early diagnosis and treatment and differentiation from SIH can cause complications and could affect the optic nerves.

Abstract Background Spontaneous intracranial hypotension and post-dural puncture headache are both caused by a loss of cerebrospinal fluid but present with different pathogeneses. We compared these two conditions concerning their clinical characteristics, brain imaging findings, and responses to epidural blood patch treatment. Methods We retrospectively reviewed the records of patients with intracranial hypotension admitted to the Neurology ward of the Pusan National University Hospital between January 1, 2011, and December 31, 2019, and collected information regarding age, sex, disease duration, hospital course, headache intensity, time to the appearance of a headache after sitting, associated phenomena (nausea, vomiting, auditory symptoms, dizziness), number of epidural blood patch treatments, and prognosis. The brain MRI signs of intracranial hypotension were recorded, including three qualitative signs (diffuse pachymeningeal enhancement, venous distention of the lateral sinus, subdural fluid collection), and six quantitative signs (pituitary height, suprasellar cistern, prepontine cistern, mamillopontine distance, the midbrain-pons angle, and the angle between the vein of Galen and the straight sinus). Results A total of 105 patients (61 spontaneous intracranial hypotension patients and 44 post-dural puncture headache patients) who met the inclusion criteria were reviewed. More patients with spontaneous intracranial hypotension required epidural blood patch treatment than those with post-dural puncture headache (70.5% (43/61) vs. 45.5% (20/44); p = 0.01) and the spontaneous intracranial hypotension group included a higher proportion of patients who underwent epidural blood patch treatment more than once (37.7% (23/61) vs. 13.6% (6/44); p = 0.007). Brain MRI showed signs of intracranial hypotension in both groups, although the angle between the vein of Galen and the straight sinus was greater in the post-dural puncture headache group (median [95% Confidence Interval]: 85° [68°-79°] vs. 74° [76°-96°], p = 0.02). Conclusions Patients with spontaneous intracranial hypotension received more epidural blood patch treatments and more often needed multiple epidural blood patch treatments. Although both groups showed similar brain MRI findings, the angle between the vein of Galen and the straight sinus differed significantly between the groups.
